Wichtels Rätselsommer 2024 (8): Kakuro-Messfehler
(Published on 17. September 2024, 20:23 by wichtel)
Once upon a magical Christmas Eve, the impish gnomes were busy making a special present for their beloved puzzle friend Niverio. As the clock struck midnight, the puzzle gnomes handed their completed creation to Santa, who was just getting ready to deliver the presents. Unable to resist the temptation, Santa decided to have a glance at it before putting it under the Christmas tree. His eyes sparkled with curiosity, as he unfolded the parchment.
"Shade some of the unclued cells, so that no two shaded cells share an edge. Enter a digit from 1 to 9 in each unshaded cell, and leave the shaded cells empty. All unshaded cells must be connected, but no 2x2 area may be entirely unshaded. As usual, digits may not repeat between two clued cells nor between a clued cell and the edge of the grid. However, there is something slightly wrong with the Kakuro measurements... it seems that the shaded cells are to be blamed. Fortunately, the nature of the interference can be determined: each shaded cell increases the measurement error by 1. If for example a clue of the value 32 sees three shaded cells, then the digits must sum to either 29 or 35."
With a twinkle in his eye, Santa placed the puzzle back into its gift wrap and secured it with a magical ribbon.
Solution code: The eighth-to-last column from top to bottom, then the sixth-to-last column from top to bottom. Enter S for shaded cells and ignore clued cells.

Sehr schönes Rätsel! Wahrscheinlich hätte ich etwas deutlich gebraucht, hätte ich den Kommentar von glum_hippo gelesen! :-D
(...oder natürlich die Anleitung schneller nochmal zurate gezogen, als ich nicht weiter kam...)

I have learned today that one can get quite far despite forgetting the no 2x2 rule! But what a great puzzle, a true battle of wits with an inanimate object! Merry Christmas Niverio, indeed!

Hat Spaß viel gemacht!
Allerdings glaube ich, es hat sich in die Anleitung ein Fehler eingeschlichen. Da steht die Ziffern dürfen sich zwischen den "schattierten Feldern" nicht wiederholen, aber es sind wohl eher die "blockierten Felder" gemeint.
